Flexible printed circuit finger trace layout for parallel servo operation

A flexible printed circuit (FPC) for a hard disk drive, the FPC comprising:

• a first preamplifier electrically connected to a first plurality of read-write transducers;
• a second preamplifier electrically connected to a second plurality of read-write transducers;
• a first section comprising first electrical traces between a first fine actuator, corresponding to one of the first plurality of read-write transducers, and a corresponding first fine actuator controller;
• and
• a second section comprising second electrical traces between a second fine actuator, corresponding to one of the second plurality of read-write transducers, and a corresponding second fine actuator controller;
• wherein in an area electrically connecting the second preamplifier with a main controller, the second electrical traces are positioned anti-adjacent to a with a write trace between the second electrical traces and a read trace.

A method of manufacturing a flexible printed circuit (FPC), the method comprising:

• forming a first section comprising first electrical traces configured for electrical connection between a first fine actuator, corresponding to one of a first plurality of read-write transducers, and a corresponding first fine actuator controller;
• forming a second section comprising second electrical traces configured for electrical connection between a second fine actuator, corresponding to one of a second plurality of read-write transducers, and a corresponding second fine actuator controller;
• electrically and mechanically connecting a first preamplifier configured for electrical connection to the first plurality of read-write transducers;
• and
• electrically and mechanically connecting a second preamplifier configured for electrical connection to the second plurality of read-write transducers;
• wherein forming the second section includes forming means for inhibiting crosstalk between the second electrical traces and at least one other trace of the second section, including forming the second electrical traces, in an area of traces configured for electrical connection of the second preamplifier with a main controller, positioned with a write trace between the second electrical traces and a read trace.
